1) General: The angle between one plane and another, or
the angle formed by a reference axis and a given line.
2) Binary systems: The angle between the plane of the orbit and the
→ plane of the sky.
3) Rotating stars: The angle between the → equatorial plane
and the → plane of the sky.

1) The angle between two lines or two planes.
2) An orbital element that defines the angle between the orbital plane of a solar system
body (planet, comet, asteroid) and the plane of the ecliptic.
3) The angle between the equatorial and orbital planes of a planet.

An → orbital element that defines the angle between the
orbital plane of a solar system body (planet, comet, asteroid) and the plane of the ecliptic.
The orbital inclination of the Earth's orbit is 0°; those of Mercury, Venus, and Mars are
7.01°, 3.39°, and 1.85° respectively.
